I did a thing.

Harry, I ordered the parts off Rockauto. I’ve talked with a few guys in the business, they have the same opinions about most aftermarket parts for A/C systems...which is lukewarm. Fortunately the compressor is still good as are the electronics.

The FSM does a good job with diagnosing and troubleshooting the HVAC. It was instrumental repairing my wife’s A/C on her 99 and buttoning up the NA.

There is a surprising amount of good info on better BMW owner forums as those systems are a little finicky and expensive to repair, so there are a lot of DIY jobs with terrific empirical data, particularly with the parallel flow condensers and Nylog sealant.
